How Many Tissue Processors Does a Lab Need?
The number of tissue processors a lab needs comes down to daily cassette (block) load, the processing cycle you run and your turnaround target. One automatic vacuum processor handles a large overnight batch; beyond that, or where uptime is critical, a second (or a backup) processor is worth planning.
Instead of guessing, model it: the Throughput Simulator takes your blocks per day, working pattern and equipment and tells you whether processing is comfortable, tight or overloaded.
It is about the batch, not the average
Processing is a batch step — capacity is cassettes per run, not per hour. A single overnight run covers most labs.
Plan for uptime
At high volume, a backup processor protects turnaround when one unit is serviced.
Reagent rotation matters
Under-processing from spent reagents wastes capacity — factor a rotation schedule in.
Will your lab keep up with its workload?
Enter your daily load and equipment and we model the real histopathology sequence — where the bottleneck is, expected turnaround, and how automation or staffing would change it.

Can one tissue processor run a whole lab?
For many small and medium labs, yes — a single automatic vacuum processor running an overnight cycle covers daily block volume. Larger or 24-hour labs benefit from a second or backup unit.
How do I know if my processor is the bottleneck?
Run the Throughput Simulator with your blocks/day and equipment — it flags processing as Comfortable, Tight or Overloaded and shows what adding capacity would change.
